used efliciently under various conditions and circumstances. These and other objects will be in part obvious and in part pointed out below.

The invention accordingly consists in the features of construction, combinations of elements, arrangements of parts and in the several steps :and relation and order of each of the same to one or more of the others, all as will be illustratively described herein, and the scope of the application of which will be indicated in the following claims.

In the drawings in which is shown one of the various possible embodiments of my invention:

Figure l is a front elevation of one embodiment of the invention partly in section;

Figure 2 is a side elevation;

Figure 3 is a plan View;

Figure 4 is a horizontal sectional view taken on the line 4-4 of Figure 5 showing certain of the operative parts; 7

Figure 5 is a vertical section on the line.5 -5 of Figure 4;

Figure 6 is a vertical section taken on the line 6--6 of Figure 1, certain parts being shown in elevation; and

Figure 7 is a perspective view of one of the pouncing pad assemblies.

Referring particularly to Figure 1 of the drawings, a casing 2 having a top wall 3 provides a base for the machine and encloses certain of the .working parts. A hat block 4 is removably held on a chuck plate 6 and has mounted thereon a hat body 8. Chuck plate 6 is carried by a floating rotatable shaft lfl which is mounted in a sleeve bearing I2 supported by a pair of arms l4. Arms l4 are rigidly connected to a sleeve I6 which is pivotally mounted (see Figures 2 and 3) on a shaft I! which is supported on the upper ends of a pair of vertical bars I8 (Figure 2). Bars l8 are rigidly attached at their lower ends to a shaft which is rockably supported by a pair of bearings on the rear side of easing 2. shaft 20 and welded to the adjacent bar I8 is a Clamped to 21 Claims. (01. 223-20) ing 2.

cam follower arm 22 which extends forwardly (to the right in Figure 2) along the side of easing 2. At its right-hand end cam follower 22 carries a cam roller 36 which rides upon a cam 32.

a driving shaft 28 which is rotatably supported by a pair of bearings 26 on the front wall of cas- Shaft 28 Figure 3 is driven from its righthand end through a sprocket wheel 30. Sprocket wheel 30 is driven froma source of power (not shown) through sprocket chain I50. As shaft 28 turns, cam 32 acts through cam roller 3%, arm 22, shaft 20, bars l8, shaft ii, and arms l4 to oscillate shaft Hl in substantially ahorizontal plane.

Mounted on and pinned to the left-hand end of shaft 28, as viewed in Figures 2 and 3, is a sprocket wheel 34 which drives a double sprocket wheel 24 rotatably mounted on the end of shaft 26 through sprocket chain" 40. A similar double sprocket wheel is rotatably mounted on shaft I1 and is driven through a sprocket chain 44 by a sprocket wheel 24. Wheel 42 through a sprocket chain 48 drives a sprocket wheel 46 pinned to shaft I0. Thus, the rotation of shaft 28 is transmitted to floating shaft [0. However, sprocket wheel 46 has twice as many teeth as has sprocket wheel 42 with the result that shaft Ill rotates at one half the speed of shaft 28.

The pouncing operation is performed by a pair of pouncing tools which are mounted with their pads 50 on the opposite sides of the brim of the hat directly beneath shaft 10. Pads 50 are made from thin spring steel, their faces are curved 'in cross section, and they include integral spring portions held together in a zone behind the central portion of the pad member. As shown best in Figure 7, each pad has a sheet of sandpaper thereon which is held in place by a pair of blocks 52 removably attached to the pad. The pad is supported by a pair of leaf springs 54, each of Theshaft extension 62 at the left in Figure .1

is supported by a pair bf bearing sleeves 66 and 68, and clamped to the shaft extension is a rocking arm 10 (see Figure 4). Attached to the opposite end of arm 10 is a crank arm 12 which has As is, best shown in Figure 1, cam 32 is mounted upon for moving one of said shaftstoward and from the other of said shafts to move said pouncing pads into and out of pouncing relationship with respect to each other, and means for rocking said shafts with a reciprocating action. in opposite phase relationship with respect to each other, whereby the faces of said pads move tangentially with respect to the brim of said hat as they pounce the brim of said hat. T

16. In a machine for pouncing a hat brim, the combination of, a support, a pair of parallel shafts, means mounting said shafts on said support for oscillating movement about their axes, a pad supporting member secured to each of said shafts, a pouncing pad attached to each of said supporting members, said supporting members extending generally toward each other whereby said pads may be juxtaposed in hat brim receiving relation to engage and pounce the opposite sides of a hat brim disposed therebetween, means for supporting said hat to position its brim between said pads, means for rotating said hat, and means for oscillating said shafts in opposite phase relationship with respect to each other thereby to swing said supporting members and accordingly said pads back and forth over the opposite sides of said brim, so that any point on the operating surface of either pad during movement thereof generates an are which lies in a plane extending transversely through thebrim of said hat and the rock axes of said shafts.

17. In a machine for pouncing a hat brim, the combination of, a pair of pouncing pads having operating surfaces arcuate in cross section, supporting means mounting said pads in juxtapositionwith portions of their operating surfaces opposed to one another in a position to receive the brim of a hat therebetween, means for supporting said hat to position its brim between said pads, means for rotating said hat, and means for driving said first-mentioned supporting means to swing said pads back and forth along arcuate paths in relatively opposed directions so that any point on the operating surface of either pad during the movement thereof generates an are that lies in a plane extending transversely :through the plane of the portion of said brim =being pounced.

18. In a machine for pouncing a hat brim, the

combination of, a pair of pouncing pads, supporting means mounting said pads in juxtaposition with portions of their operating surfaces opposed to one another in a position to receive the brim of a hat therebetween, means for supporting said hat to position its brim between said pads, means for rotating said hat, means for driving said -first-mentioned supporting means to swing said. pads back and forth along arcuate paths in rela-' with the end of one of'said pads during the pouncing operation.

19, In a machine for pouncing a hat brim, the combination of, a pair of pouncingfpads having arcuate operating surfaces, a pairof supporting members mounting said pads in juxtaposition with portions of their operating surfaces opposed to one another in a position to receive the brim of a hat therebetween, means for supporting said hat to position its brim between said-pads, means for rotating said hat, means for idriving said supporting members to rock said pads back and forth along arcuate paths in opposite phase relationship in respect to each other-so that any point on the operating surface of either pad during the movement thereof generates an are that lies in a plane extending transversely through the plane of the portion of said brim being pounced, means mounting at least one of said supporting members for movement toward and from the other supporting member, and means operatively associated with said last-mentioned means for moving said movable supporting member toward and from the other supporting member and thus moving said pouncing pads towardand from each other or into and out of pouncing'position with respect to each other.

20. The herein described method of pouncing the brim of a hat which includes the steps of, rotating the hat about its axis, and pouncing opposite sides of the brim of saidf' hat by curved pouncing surfaces in such a manner that a given point on' either surface engageable'with the brim moves with an oscillating motionin an arcuate path that is tangent to the surface of the brim being pounced and that lies in a plane extending transversely through the plane of the surface of the brim being pounced.

21. The herein described method of pouncing the brim of a hat which includes the steps of, rotating the hat about its axis, bouncing opposite sides of the brim of said hat by curved pouncing surfaces in such a manner that a given point on either surface engageable withithe brim moves with an oscillating motion in an arcuate path that is tangent to the surface ofrthe brim being pounced, and that lies in a plane extending transversely through the plane of thefsurface of the brim being pounced, and moving-the axis of rotation of the hat back and forth relative to the plane of said arcuate path in timed relation to the movement of the pouncing surfaces along the brim of said hat and in a path substantially normal to the plane of said arcuate path.
